The record's label does not equal the term's primary label 'EDTA disodium salt (anhydrous)'; preferred_term 'Na2-EDTA' matches the ChEBI synonym 'Na2-EDTA' on CHEBI:64734. The schema defines EXACT_MATCH as a direct match to the term and SYNONYM_MATCH as a match to a known synonym, so the recorded grade overstated. ontology_id is unchanged — the term is correct. The own-identifier SSSOM predicate remains skos:exactMatch under Rule D (#438), independently of mapping quality. | |

The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).

Tokens already present on the kg-microbe ontology node were left out as redundant (#520). |
